M38510/07903BEA

Overview

M38510/07903BEA is a military-grade quad 2-input multiplexer manufactured by Texas Instruments. It operates within a temperature range of -55 to 125 °C and utilizes a 16-pin ceramic dual in-line package (CDIP). The device functions as a high-speed logic circuit designed for signal routing applications.

Feature Summary

• Provides four independent 2-to-1 data selection channels
• Features military-grade reliability and extended thermal tolerance
• Utilizes ceramic dual in-line packaging for robust physical protection

Applications

• Military defense systems requiring high-reliability signal switching
• Avionics equipment operating under extreme environmental conditions
• Spacecraft telemetry and control circuits

Procurement Notes

Verify the specific ordering suffix to confirm the exact package configuration, as the base part number corresponds to multiple variants including CDIP and CFP options. Confirm RoHS exemption status and lead finish specifications directly with the manufacturer or authorized distributors prior to acquisition.

Selection Notes

Select this component when designing systems that require certified military-grade performance standards. Ensure the application environment aligns with the specified wide temperature operating range. Verify that the 16-pin CDIP footprint matches the target printed circuit board layout constraints.

Part Context
